Özet
The growth and mortality rate of different size of mussels, Mytilus galloprovincialis, were compared in Mersin bay, Izmir. Mussel sampling was performed on a monthly basis over 1 year, together with hyrobiological parameters. Water temperature, salinity, chlorophyll a, total particulate matter (TPM) and particulate organic carbon (POC) were determined. Average chlorophyll a, TPM and POC values were 3.88 +/- 1.62 mu g L-1, 13.12 +/- 3.68 mg L-1 and 252 +/- 121.89 mu g L-1 respectively. Initial mean lengths of mussels for each size group were 10 mm (9.91 +/- 0.25 mm), 20 mm (20.14 +/- 0.29 mm), 30 mm (30.66 +/- 0.21 mm), 40 mm (40.14 +/- 0.21 mm), 50 mm (50.62 +/- 0.21 mm), 60 mm (59.77 +/- 0.21 mm) and 70 mm (69.47 +/- 0.62 mm). Maximum growth in length occurred during the spring-summer months. The annual length increments of mussel size groups were 46.22, 41.42, 30.3, 28.03, 20.63, 16.34 and 12.03 mm from small to large size groups respectively. Small mussels grew faster than large mussels and reached commercial size at the same time. Mortality was < 5% for all groups at the end of the experiment.
